Abstract
The epitaxial growth of nickel and copper (111) silver has been investigated in ultra high vacuum using LEED, RHEED and Auger spectroscopy. At 570K island growth is observed in both cases, but with substrates close to room temperature more extensive flat deposits are formed. On heating, these deposits are found to draw up into more pronounced three dimensional islands. These results are shown to be consistent with surface energy and diffusion data. Some comments on the relative merits of the three analysis techniques are also presented.
